"It's a badge, a badge from the Guardian family. ”

After listening to Dumbledore's explanation, Tang Yuan understood.

It's not just a badge, it's also a portkey.

Through this badge, Tang Yuan could go to that secret family on his own.

Moreover, unlike ordinary door keys, this badge is specially made, and the space teleportation function attached to it is also equipped with a protection function, as well as a small trigger module, which is just convenient for ordinary people like Tang Yuan who have not embarked on the road of qi refining.

After all, the fields involved in spatial teleportation are very profound, and at the same time, the cultivation requirements for users are also very high.

Compared to the portkey that appeared in the Triwizard Tournament at that level in Tang Yuan's memory, he still felt that this kind of doorkey with its own departure module was better.

After all, in Tang Yuan's previous life, anti-mistouch has penetrated into all walks of life.

After chatting about business and gossiping, the most important question is here-

"That's... Professor, how do I get back?"

This is indeed a very important question, Tang Yuan came to Hogwarts from the Leaky Cauldron Bar, crossed a long distance, and was not harmed by spatial teleportation, but this is because the portkey made by Old Deng Tou is more reliable.

When he was just teleported, Tang Yuan had already consulted the system, I don't know if it was because he started to contact these contents, this time the system did not hide anything, and directly conveyed some basic content.

In this world, the way in which the Qi Refiners are in a hurry is generally divided into several types-

First, the easiest and most direct way, walking...

Well, this is pure nonsense, but there is also a difference between walking and walking.

After all, they are all Qi refiners who have achieved cultivation, and there are still some tips for hurrying, such as shrinking the ground into inches, walking on water, and walking leisurely, all of which can increase their movement speed to a certain extent.

The second method is with the help of transportation.

For example, Tang Yuan previously noted the sentence at the end of the list in the admission notice - Note 2: Parents are specially reminded that first-year freshmen are not allowed to bring their own flying skateboards!

That's right, a flying skateboard!

Unlike the wizard world in Tang Yuan's memory, this is the world of qi refiners after all, and everything has been metamorphosed.

Naturally, the wizard who was mentioned in the previous life rode a broomstick, and when he arrived here, he also became a flying skateboard.

However, according to the system, in the earliest period, these Qi refiners also flew with Edgeworth, but unfortunately, in order to distinguish themselves from the Eastern Continent and expand the market, they developed toys such as flying skateboards.

In addition to flying skateboards, some other similar products have also been produced one after another-

For example, the flying carriage with the flying formation inscribed, and then with the solidified flying charm, and some messy functional modules.

Or something like a flying couch, flying toilet or something like that.

These items all belong to the category of tools.

The first walking plan is too much about the Qi Refiner's own cultivation and the amount of true yuan stored in the body, while the second plan is slightly better, after all, these tools are not natal magic weapons, and they don't need to consume their own true yuan too much, but they still need energy supply.

And in addition to these two options, there are three other options.

Among them, the most widely used and the most used is Floo.com.

But in Tang Yuan's opinion, this so-called Feilu Network is equivalent to the teleportation array in the online game in the previous life.

Or is it a simplified version of the plane-world teleportation shuttles in the Origin World?

However, the system did not inform the use of Floo.com, and Tang Yuan guessed that this part of the information should also need to be charged.

In addition to the Floo network, another widely circulated method that Tang Yuan has already experienced, that is, the portkey.

Most of the portkeys are one-time items, using the way of talismans, the power of spatial teleportation and spatial coordinates are stored in the items, and the huge energy required for spatial teleportation is instilled, and a complete doorkey can be successfully crafted.

Of course, the portkey used by Tang Yuan was just an admission letter, which required a strong talisman foundation and a qi refiner who could power the portkey.

That's right, if Hagrid hadn't activated the portkey and provided the True Element Aura for the teleportation, this envelope would have been just an ordinary letter of acceptance.

However, unlike Floro, the use of the portkey does not require a teleportation array at the target location, only a spatial coordinate is needed to successfully teleport, therefore, after using the portkey, under normal circumstances, it is necessary to use other portkeys, or use other methods to leave and return.

That's where the inconvenience of a door key comes in.

However, it is not without its advantages, some hidden activities, or if you want to travel to a location that has not yet built a Floo network, then the Portkey is the best choice.

In addition, the portkey generally does not limit the number of users, as long as the portkey can be touched, then it can be teleported out by the space array inside the doorkey.

Of course, if the number of people exceeds the reserve energy in the door key, the Qi Refiners can also choose to consume their own True Yuan to ensure the success of the teleportation.

In addition to the Floo Net and the Portkey, there is also a special spell that can also achieve the effect of spatial transfer.

Phantom Shifting!

Or it can be called a noun such as shapeshifting and teleportation, which is also perfectly fine.

It's a pity that, according to the system, if you want to successfully learn this spell, you need at least the cultivation of the Yuan Infant Stage.

But it doesn't matter, as a world of gas refiners with a crooked technology tree, the great ancestors of gas refiners have developed a special auxiliary item, which is somewhat similar to the basic talisman on the door key, which can effectively assist the gas refiner to phantom transformation.

As a result, the standard of phantom shifting has been lowered by one level, and it only needs to be above the middle level of infancy to be cast.

Similarly, due to the need for separate charges, the system did not explain Tang Yuan in too much detail.

However, just these contents have already opened Tang Yuan's eyes.

The topic came back, Tang Yuan was really concerned about this issue at this time, and was pulled over by Lao Deng Tou with a door key, this is very simple, but the most critical question, how should he go back?

Is it really necessary to go to the system to spend a few invincible points to unlock the instructions for using the Floo Network?
